panel data from 283 prefecture-level cities from 2010 to 2020 in China

This analysis is based on a balanced panel dataset of 283 prefecture level cities in China from 2010 to 2020. The list of cities designated as SC pilot cities comes from official announcements released by the Ministry of Housing and Urban Rural Development (MOHURD) in three batches (2012, 2013, and 2014). The year in which a city is included in the pilot list is defined as the policy implementation year. The data of mechanism variables is collected from specialized sources. The data on information transmission efficiency comes from the government informationization evaluation report of the Ministry of Industry and Information Technology. Departmental coordination efficiency data is manually collected from the local municipal government's public document database. The data of mechanism variables is collected from specialized sources.

Departmental coordination efficiency data is manually collected from the local municipal government's public document database. To ensure data quality, the raw data undergoes strict cleaning. Cities with severe data loss (such as municipalities directly under the central government) are excluded. Extreme values of disaster response time (exceeding 72 hours) are considered missing data to avoid the impact of outliers. All continuous variables are randomly sorted at the 1st and 99th percentiles to mitigate the impact of extreme values.
